Thanks, Stephane, and hello, everyone. Today, I will provide an overview of our financial results for the third quarter and share our outlook for the remainder of 2025. Let's start by reviewing our commercial performance, which you can follow on Slide 7. Year-to-date, total revenue was approximately $1.3 billion with $900 million from the U.S. and the remainder from international markets. In addition to product sales, revenue also includes collaboration, grant and stand-ready revenue associated with our strategic partnerships. For the third quarter of 2025, our total revenue was $1 billion. U.S. revenue was $800 million in the third quarter, the vast majority of which was from our COVID vaccines, which included the successful launch of our new COVID vaccine, mNEXSPIKE. Stephen will give more detail on the U.S. COVID vaccination season in a moment. Revenue outside the U.S. was $200 million. Approximately half of international revenue in Q3 was delivered to Canada where we began executing on our strategic partnership through our in-country manufacturing facility. As a reminder, we have similar strategic partnerships with the Australian and U.K. governments and expect to begin shipping locally manufactured product in 4Q '25 and 1Q '26, respectively. For the full year 2025 outlook, we are narrowing our revenue range to $1.6 billion to $2 billion from our previous guidance of $1.5 billion to $2.2 billion. For the U.S. market, we expect fourth quarter sales of $100 million to $400 million. This would bring our updated full year U.S. revenue guidance to $1 billion to $1.3 billion versus our prior guidance of $1 billion to $1.5 billion. Our original guidance assumed year-over-year revenue to be flat to down 33%, excluding onetime items. Our updated guidance now assumes a year-over-year decline of 15% to 33%. COVID vaccination rates remain the largest variable to this range, which Stephen will walk through in a moment. For international markets, we now expect revenue to be between $300 million and $400 million in the fourth quarter, bringing the full year to $600 million to $700 million versus our previous guidance of $500 million to $700 million. We have a tighter range on our international sales as most of these sales are for contracted volumes leaving delivery timing and file vaccination rates as the only remaining variables. Moving to Slide 8, I will review our 3Q financial results in more detail. Total revenue was $1 billion in the quarter, as I just discussed on the prior page. We had net product sales of $973 million and other revenue of $43 million from grants, collaborations, royalties and stand-ready fees. The 45% year-over-year decline in revenue was expected and primarily reflects lower COVID vaccine demand. It's also worth noting that last year's third quarter included approximately $140 million from a true-up adjustment to prior period sales provisions. That benefit did not repeat in Q3 this year. Cost of sales for the third quarter was $207 million, representing 21% net product sales for the quarter. This was a 60% year-over-year decrease in our cost of sales from $514 million in Q3 last year. The improvement was driven by lower inventory write-downs, reduced unutilized manufacturing capacity and lower volume. Overall, these results reflect the productivity gains and the efficiency improvements we've achieved in our manufacturing operations. R&D expenses in the third quarter were $801 million, a 30% decrease from last year. The reduction mainly reflects lower clinical trial costs as we completed several large Phase III studies in our vaccine portfolio as well as efficiency gains across the organization. Last year's results also included an expense related to the purchase of a priority review voucher. SG&A expenses were $268 million in the third quarter, a 5% decrease year-over-year. The decline mainly reflects lower consulting and external service costs across multiple functions, along with reduced digital and facility spending. These savings reflect the cost discipline we've built into the organization and our continued focus on streamlining how we operate. Our income tax provision for the quarter was immaterial, consistent with the prior year. We continue to maintain a global valuation allowance against the majority of our deferred tax assets, which limits our ability to recognize tax benefits from losses. Net loss for the quarter was $200 million compared to net income of $13 million in Q3 2024. Loss per share was $0.51 compared to earnings per share of $0.03 last year. We ended Q3 with cash and investments of $6.6 billion, down from $7.5 billion at the end of Q2. The decrease was primarily driven by seasonal impact to working capital. With that, let me take a minute to share the progress we've made on our cost reduction goals. As a reminder, our original target this year was to reduce our GAAP operating expenses from $7.2 billion in 2024 to $6.4 billion in 2025. On a cash cost basis, excluding stock-based compensation, depreciation and other noncash charges, that represented a decrease from $6.3 billion in 2024 to $5.5 billion. I'm happy to report that we are now on track to beat our 2025 cost plan by over $1 billion on a GAAP basis and by $900 million on a cash cost basis, both at the midpoint of our projections. During our previous 2Q call, we have lowered our GAAP and cash cost by $400 million each, with GAAP costs lowered from $6.4 billion to $6 billion, and cash costs lowered from $5.5 billion to $5.1 billion. Today, we are further lowering our 2025 expense guidance due to additional progress across the company to drive efficiency gains and continued investment prioritization. Our GAAP operating expense guidance is being reduced by another $700 million from $6 billion to $5.3 billion at the midpoint. This reduction is $500 million of cash costs, plus $200 million of noncash reductions in stock-based compensation and depreciation. The $700 million GAAP reduction from prior guidance is split evenly between cost of sales and R&D. We are lowering our cost of sales forecast by $300 million to $400 million from $1.2 billion to a range of $0.8 billion to $0.9 billion, which reflects an acceleration of the efficiency programs we are targeting as part of our multiyear cost-out plan. We are also lowering our R&D expense range to $3.3 billion to $3.4 billion and approximately $350 million improvement due to continued investment prioritization and efficiency gains in the execution of our clinical trials. In just 2 years, we expect to reduce our cash cost by approximately 50% from nearly $9 billion in 2023 to $4.6 billion in 2025. We are now ahead of our plans, and we'll update improvements to our 2026 and 2027 targets at our upcoming Analyst Day on November 20. Importantly, we continue to target cash breakeven in 2028. I would like to take this moment to thank all my Moderna colleagues for their hard work and commitment to improve the financial profile of our company. Moving to Slide 10. I will share our updated 2025 financial framework. For total revenue, as I mentioned in my earlier remarks, we are narrowing our range to $1.6 billion to $2 billion from our previous guidance of $1.5 billion to $2.2 billion. For cost of sales, our updated guidance is $0.8 billion to $0.9 billion, an improvement from our previous guidance of $1.2 billion. This updated range assumes a higher cost of sales in 4Q versus 3Q, which factors in similar sales volume and higher unutilized manufacturing charges. Newly introduced tariffs are not expected to have a material impact on our business, but we continue to monitor changes to global tariffs. Our revised R&D range of $3.3 billion to $3.4 billion projects an increase in 4Q spend due to the seasonality of vaccine trial spend as well as studies in support of regulatory approvals. SG&A expenses are expected to be $1.1 billion. Similar to last year, we expect SG&A expenses in the fourth quarter to increase primarily due to commercial related activity. We expect taxes to be negligible in 2025. We expect our capital expenditures are also supposed to be approximately $300 million. We are increasing our year-end cash guidance to $6.5 billion to $7 billion, an increase of $0.5 billion to $1 billion from our prior guidance of approximately $6 billion. This increase is projected to increase year-end cash due to the reduction in our operating expense for the year. In summary, we have made strong financial progress against our 2025 financial objectives. We have tightened our sales range because of increased visibility into our seasonal sales. And we have lowered our 2025 cash cost estimate by $900 million from $5.5 billion to $4.6 billion, resulting in a higher projected year-end cash balance of $6.5 billion to $7 billion. With that, I will now turn the call over to Stephen.
